I tried this yesterday on my W510 and everything went pretty smooth using your files. I had to install the PXHCD.KEXT found on page 9 to get USB 3.0(super speed) working.
I am using Clover-boot with your attached files.
I ordered the Atheros AR5BHB9 and hopefully it will just work when i get it.
The only 2 things I dont have working are the SD Card Reader and Adjustable Brightness.
For the SD Card Reader it sounds like no one has gotten that to work and to be honest, i dont care much about it. But for the Adjustable Brightness i have tried using the DSDT.aml from the "Extra" folder of your "W510-Files.zip" as well as the other DSDT.aml file from your https://www.dropbox....r-Thinkpads.zip since mine is the
W510 with Quadro 880M but the FN+home/end doesnt affect brightness once the Mountain Lion Login screen appears. I've read about a slider in the "Display settings" as well, but don't see it. Unplugging the laptop doesnt affect it either.
Is FN+home/end still the correct hotkeys? Sorry for the ignorance (I'm a hackintosh noob), but should i be doing something with the .DSL files? I am unsure of their purpose.
Lastly, how do i know or how can i tell if speedstep and turbo are working?
